ATHENA R4856-213 Cylinder Head/Base Gasket Kit for Yamaha YZ 450 F

The ATHENA cylinder head/base gasket kit for Yamaha YZ 450 F is designed for riders who want to maximize the performance of their competition engine. This kit includes a cylinder head gasket and two base gaskets, one of which has the original thickness, while the other is reduced by 0.1 mm. This versatility allows for precise management of the cylinder height on the engine block, optimizing the squish and improving compression in the combustion chamber.

ATHENA gaskets are the result of careful study of the specifications of original engines, ensuring a perfect fit to the parameters required by manufacturers. Thanks to low moisture absorption and resistance to oils and fuels, these gaskets provide reliable performance even under extreme conditions. The ease of application and removal is an additional advantage, as there is no need for silicone-based sealants to ensure a flawless seal.

The R&D department of ATHENA has dedicated time and resources to identify critical areas of the engine, applying wear-resistant and sealing treatments where necessary. Using innovative materials such as Motorgasket®, developed in the research laboratories of the ATHENA Group, the kit ensures optimal sealing even under thermal and mechanical stress. With this kit, every rider can achieve the ideal engine setting, ensuring high performance at a competitive price.
